[legacy rsk]

So basically just the Rev D and Rev E that can be reflashed?

Yeap. I went looking to do my car and is a no go revision B

[mulligan]

Well the part is now installed:

Pro's:

No CEL codes at all, ECU reading all OK
Car pulls like a train from 3500-3800 RPM, never stops
NO VOD as the car feels like a single, daily driving is OK
boost is steady at 12 psi with no oscillation

Negative:

It is very loud, the muffler (Fujitsubo Legalis R) has no resonator.
It doesn't sound like a true boxer (I miss you unequal length), my car used to sound sweeeeet as butter, it's kinda harsh, ordered a HKS silent power to counter this.
there is aprox 15% more vibration than usual
The car in 3rd and 4th is scary fast, as in geez is that 180 already?


Neutral:

Gas comsuption is OK, feels


Review:


I never ever had a good experience with the sequential system, it was all over the place, even with a refurbished black box and vaccum lines, premium gas and all it was never a quick car, it felt sluggish.

I lost refinement due to the noise, but that can be cured...


If I had to pay 1000 US for this, I'd probably be ok, since it was practically free I feel happy with the performance so far.

HOWEVER a tune is necessary according to my tech to make sure fuel is correct, if this car is tuned right and I iron out all the noise this could be a seriously quick car, especially at the target 15 psi I want to run.


I'll update to keep you all informed in this manifold in case anyone decides to install one....

Any (drivers POV) vids?

I'll see if I can record one....

I find it surprising that you're not considering reliability and longevity with this all.

The vibration you'll find is because the two turbos aren't exactly equal in size, thus not being a true parallel setup. This will ultimately decrease your longevity significantly, especially since the early rev Gen3 motors are known to be not the best EJs going.

And the Fujitsubo is loud on anything but a twin.

And its only running 12psi? What exhaust are you running?

2.5 Fujitsubo Legalis R, the Dpipes are SYMS 2.5 as well...

Longevity is something to keep my mind on, but this is a 50,000 KMs 2001 B4 with fresh turbos (I had an extra lying around from a friend's single conversion VF23, he is having a nightmare making it work..), the car was not modified prior (only an exhaust) to this and compression and leak test are perfect, the vibration I mention is barely noticeable, and it happens ONLY on IDLE, in WOT it feels exactly the same as before.

Also, you think running 1.4-1.6 BAR (like most people are) is not affecting longevity? This isn't some part made in a garage, this is a SYMS part made from excellent materials, For this car the sequential and 24 maze of vaccum lines has always been a nightmare, I was never happy with how it worked. Now with only noise to take care of and other things to tune out, I feel that it was worth it and decided to share this info as there is none outside of Japan.

Cost was zero, I installed it with a mechanic friend.


I DO NOTE, that if your sequential is running PERFECT, no VOD, no issues with the blackbox or switchover system and has a quality, I see no reason to pay for this exhuast, but in my case, I feel I have a fair trade off....

[buzzda]

Thanks for sharing, it's good to see different things being tried and I'm glad your happy with it, but, I think a (good) tune (which you still need by the sounds of it) would've fixed the problems you've described with the TT system... Anyway, look forward to the seeing the vid.

Hi! My name is Clodoaldo Barros,from AutoMirr for speed planning (Macau),i will install this SYMS exhaust manifold tomorrow,i want to know do you continue using the intercooler intake valve and the down pipe exhaust valve? and the ECU is working properly? and how about the engine light?

Best regards

I wish i had a cool name, like Clodoaldo.

The 2nd turbo IC valve leave open (remove vac hose No 1 leave open to air )
Exhaust Control Valve with its BIG actuator has to be totally removed.

Hi! Mr.Walts! Thanks for your msgs,im happy! And Mr.Zazarah thanks for your reply as well,i have do the same what you suggested to do,the car is running in good performance,is just like a natural aspirated car,this header is really made for race use,top end power only and eliminate totally the sequential system,im planning for e-manage ecu setup,and also planning back to stock,dunno what to do....

Agreed the Syms headers are really for racing.
A split Twin-scroll.
What TT turbos are you using?

Im using the standard B4 RSK turbos,they are almost the same size,no problem at all,very stable,and still can listen the boxer rumble,is near equal lenght.

[Jimbo]

i read this guys ^ posts in a russian accent, hilarious!

[mulligan]

A bit long term update for the SYMS, so far no issues, just that sound... the exhaust won't cure it, so I guess is now with a proper silencer that won't affect performance... the check engine light never comes in, 13-14 psi stable, compression OK...

I still maintain, if I had to pay us1500 for this, forget it...

Video coming soon!

Unless I sell the car for a new Legacy GT

[Soop]

I'm sorry all this effort and you're running a 15.7?

I could run faster then that. My sisters VP commo runs 16 flat and its rooted.

[neni]

i'm runnin the syms dumps and they are bomb beat!

[BigWillieStyles]

A few of the NZ guys are running parallel systems. Personally, I would prefer a tune with some sort of piggyback.

... especially since the early rev Gen3 motors are known to be not the best EJs going.

Im curious where you heard this from? I thought all BH/BE twin turbos had the same block (EJ206 and EJ208)? Biggest difference was the tune which was much more susceptible to pinging and leaning out on the late models.

video after installation,for the check engine light is on because of the SYMS RACING ECU trade in,is normal.

Nice car. Bit of a different sound with those headers.
I noticed that you haven't unplugged the secondary's bypass valve. This could be causing the CEL as it will be venting all boost below 4000rpm creating uneven pressure build up between each turbo. The differential pressure sensor will notice this and throw out a code. If this is the case it will be seriously hampering performance too. I would disconnect the vac line from the black box and plug it up, then tee the bypass valve into the blow off valve coming off the intercooler.
